From the international full year to the Japanese bad year, the Korean false year and the Islamic Hijri calendar, one birth date can see you in different time and space.
Results are automatically calculated based on today's date.
Once you select your birth date, you can view six age algorithms.
Accurately record every period of growth
Each region has its own time language.
Traditional virtual age, zodiac signs, stems and branches
The traditional calculation is one year old at birth and one more year old during the Lunar New Year; it is different from the full year old used by law or passports.
And the calendar year number and bad year reminder
According to folk custom, men aged 25, 42, and 61 years old and women aged 19, 33, and 37 years old are considered bad years. Different shrines and regional practices may differ, so please refer to this for cultural reference.
Full age, Korean age, age in years
The daily traditional age in Korea is one year old after birth and one year old on New Year's Day; current legal principles take full age, and age in years is only subtracted by years.
Buddhist year and birth protection
The Thai civil Buddhist calendar is usually the AD year plus 543. For example, 2026 AD is the Buddhist calendar year 2569; the age itself is still calculated based on the birthday.
Pure lunar calendar and Hijri age
The Hijri year lasts about 354 or 355 days, which is about 10 to 11 days shorter than the Gregorian calendar; therefore, the same period of life will pass through more Hijri years.
The days you have passed
Calculated based on whether the birthday has passed or not, it is the age used in laws, passports and most international situations.
The Chinese fictitious age and the traditional Korean age are counted as one year old at birth and increase together with the New Year.
The Japanese calendar, the Buddhist calendar and the Hijri calendar use different year systems; the results are for cultural exchange and daily reference.
There is not just one answer to age: the calendars, traditions and legal systems adopted by each country determine how old you are. This tool will preserve the context of each system and assist in cross-border travel, cultural exchange and document reading.
The "virtual age" in the Chinese context is usually one year old at birth and increases during the Lunar New Year. The zodiac sign is based on the lunar year of birth as a common reference; if you are born around the Lunar New Year, the zodiac sign may need to be confirmed based on the Lunar New Year of that year. Formal documents and legal matters are still based on the Gregorian calendar date of birth and age.
Japanese daily and official documents use era names such as Reiwa, Heisei, and Showa. This page converts birth dates into Japanese calendar format and provides reminders of the folk customs of the Year of the Ox; the Year of the Ox belongs to shrine culture and is not a medical, insurance or legal determination.
In recent years, South Korea has unified the principle of full age in administration and law, but the traditional Korean age is still often seen in conversations, media and community culture. The annual age is the current year minus the year of birth, regardless of whether the birthday has passed.
The Thai Buddhist calendar, used in government, schools and daily dates, differs from the Gregorian calendar by 543 years. Age will not change; this tool also displays the guardian Buddha and colors in Thai culture according to the day of birth, for folk entertainment reference only.
The Islamic Hijri calendar is based on the phases of the moon and has 12 months in a year, which is approximately 10 to 11 days shorter than the Gregorian calendar. This page converts Hijri dates and ages based on the browser's standard calendar data; for religious festivals or official events, the moon viewing results published in the location should still prevail.
Visa, medical, educational, financial and legal documents are usually based on the Gregorian calendar date of birth and age shown in the passport or official ID card. The false year, bad year, zodiac sign and guardian color are suitable for cultural exchange and personal exploration and should not be used as a formal qualification determination.
Yes. All results are calculated based on the local date of the day you opened the page.
The Hijri year is shorter and more Hijri New Years pass through in the same period, so the numbers are usually slightly larger.
No. Please refer to the issuing unit, passport, ID card or local government regulations.
